accompanying drawings, and to the` refer-k ence-numerals marked thereon, which form part of this specification.

The object of my invention is to provide an improved typewriter wherein neither the platen nor type bar basket have to be moved in shifting from lower to upper case letters .but the shift is made by means which render operative one of two connections from a single key lever to two type bars and keeps the other connection inactive.

Figure 1 is a vertical sectional view of a typewriter having my construction, with the shift operated but not the 'key lever. Fig. 2, is a similar view of the moving parts showing the key lever depressed and the parts in -resulting position, the shift having'been o elated. Fig. 3 is aside elevation of tie shift mechanism and behind it the key lever and its immediate connection. Fig. 4i, is a side elevation of the key lever 34C.V Fig. 5 is a side elevation of the shift lever 38. Figs. 6 and 7 are side elevation and plan views respectively of the pair of wings 31 and 31a. Figs. 8 and 9 are side elevations of the stirrups 33 and 33a, taken from positions at right angles to each other. Figs. 10 and 11 are similar views of the stirrup lever 45. Fig. 12 is a plan view of some of the type bars in the rest.

Referring to the drawings in a more particular description, 20 is the frame of a typewriting machine of the usual construction and having a segment 21 to which are fastened the hangers 22 carrying the type bars 23 pivotally mounted at 24:. The swinging end of the type bars 23 are supported in normal position in the usual semicircular rest 25 and are adapted to describe an arc of about degrees in moving from the rest to their printing position on the face of the platen 26.

The type bars 23 at their pivotal end are provided with a bell crank portion to which one end of the connecting rod 27 is attached,

attached to one arm of a bell crank 28. The bell crank 28 is pivoted upon ahanger 40 which is integral with or supported upon a segment-29 which is rigidly secured to the frame 20. crank .28 is attached one end of the connecting rod 30 the other end of which is attached to. the upper point of the wing 31. rIhe wing 31 is pivotally mounted at 32 between and isrigidly `attached to the key lever 34:. The wing is shaped as shown more particularly in Fig. 6, with its swinging end form` ywhile the other end of the connecting rod is so To the other arm of the bell f5.5 the two sides of the stirrup 33 which incloses f other slot 36. When the key lever 34 is in y normalk position, that is not depressed, the lower edge of the wing 31 rests upon or near the upper edge of the key lever 34,

which `has a depression 34a to receive the lower point of the swinging edge of the wing. Oppositely disposed on the samekey lever 31, and similarly pivoted at 32a to a stirrup 33a similar to stirrup 33 is a similarly shaped wing 31a, having slots in itsarc face 85a and 36a directly opposite and corresponding to slots 35 and 36 of wingBl, the

arc faces of wings 8l and 31n being towardy each other and as near together as is possible without interfering with their free separate motion on their respective pivots.

To a point near the upper swinging edge of wing 31a is attachedl a connecting-rod 30EL the other end of which is connected'to oney arm of a bell crank 28a.pivoted upon a hanger 40a supported upon the segment 29.

For greater convenience in assembling and to get more room for operation the hangers 40 and 40 are arranged on opposite sides of the segment 29. To the other endl of the arni 28a is attached the connecting rod 27a the other end of which is attached tothe bell crank portion of a type bar 23a which is manner as 23, by a hanger secured tothe segment 21. In Fig. 1 type bar 23l is behind type bar 23 andhidden thereby except for a part of its pivoting end and its type. The two separate type bars 28 and 23a connected as described to one key bar each carry but one type which will be the type of the upper and lower case respectively and which are commonlycarried on one typebar and a 110 y mounted next to type bar 23 in a similar shift made in the machine so that only one of the type prints.

For compactness of machine and ease of assembling and to prevent any interference in operation, 1 pivot one type bar as 23 farther out from the segment 21 than the other typebar as 23, and so have the type on type bar 23 rest in the basket beyond the type of type bar 23 as the type bars are of uniform length. ment of the type which is the widest part of the type bars allows the type bars to be placed closer together and still allow the type bars to be operated without their type touching adjacent type or type bars.

Jabove the opposing faces of the wings and extending transversely across the saine is a rock shaft 37 pivoted at its ends 37 into the frame 2O and carrying adjacent to the inner sides of the frame a shift lever 38 which is a bell crank, one arm of which is the horizontal shift lever 39 extending forward to a convenient place for operation by having its shift key 41 depressed by the operator. The other arm 42 of the shift lever 38, extends downward to a` point a little below the lower edge of the key levers 34 below the depression 34 therein. Connecting the lower ends of the arms 42 is a universal shift bar 43 which is engaged by a slot 44 in the lower end of a stirrup lever 45. One of these stirrup levers clasps each key lever 34 and is pivoted thereto at 46 which point is directly on a line below the point of nearest contact of swinging or arc edges of the wings 31 and 31. The two sides of the stirrup lever 45 extend upward and are connected at their upper ends by an individual shift bar or pin 47 which will engage either slot 36 or 36 of wings 31 or 31 respectively.

On a line with slots 35 and 35 of wings 31 and 31, a universal locking bar 48 eX- tends from the arm 42 on one shift lever 38 to the other, and on a line below the rock shaft 37. A spring 49 preferably secured to the arm 42 of the shift lever 38 and attached to the frame 20 at a convenient place, keeps the arm 39 elevated except when depressed by the operator and accordingly the shift lever is in the opposite position to that shown in Fig. 1, and in position preferably of course to operate the lower case type without operating the shift.

The operation of the typewriter is as follows: Assuming the shift to be in the normal position just mentioned, to shift to upper case type the operator depresses shift key 41 which forces the arm 42 of the shift lever 38 to the right as viewed in Fig. 1, to the position shown in Fig. 1, with the arm 42 swung to the right. This motion of the arm 42 carries the universal locking bar 48 to the right and causes it to enter the series of slots 35a of wings 31a, thereby locking all This staggered arrange-` of said wings 31ai from movement and so locking all of the series of type bars 23 in their resting position in the basket 25. The same right hand motion of arm 42 of the shift lever 38, has carried the universal shift bar 43 to the right which in turn has carried with it to the right the lower end of all the individual shift levers 45. Each of these swinging on their pivots 46, have their upper ends moved to the left, thereby carrying their individual locking pins 47 into vthe.

slots 35 of wings 31. ln this position wing 31 is locked to the key lever 34 by means of shift lever 45 kpivoted to the key lever at 46 and engaging slot 35 of wing 31. Vith the parts in the last described position which is as shown in Fig. 1, upon the operator depressing the key of key lever 34 wing 31 will by reason of locking bar 48 be held at its swinging end in position and so not operate the type bar 23 or the intermediate connections, though wing 31 will change its position relative to key bar 34 by reason of the key lever going downward and carrying with it pivot 32 upon which the wing 31 will swing apart from key lever 34. But this downward motion of key lever 34 will carry with it wing 31, on account of their being locked together as before described. Thereby a downward pull will be given to rod 30 which will so operate bell crank 28 as to give a pull through the rod 27 upon the -bell crank portion of type bar 23 causing the latter to come yto printing position as shown in Fig. 2. Upon the pressure upon the key lever 34 being removed that will be returned to normal position by' reason of a spring 50 connecting the key lever 34 and the frame 20. It is also evident that as soon as the pressure upon the shift key 41 is removed the shift lever will return to normal position, and the arm 43 will move to the left as viewed in Fig. 1, carrying with it the universal locking bar 48 into slots 35 of wings 31 thereby locking wings 31 and type bars 23 in normal position as described with regard to wings 31 and type bars 23. Thisleft hand movement of the arm 42 will also carry with it universal shift bar 43 thereby moving the individual shift bars 47 in the upper end of stirrup levers 45 into engagement with slots 36a of wings 31 which will then be locked to their associated key levers 34 which in turn will through said wings 31a be operatively connected to type bars 23 in the manner heretofore described in detail as to wing 31 and type bar 23.
